Public Health France reports 1,243 excess deaths in July due to heat, bringing the provisional heat-related death toll to 7,300 since late May. Despite a slightly less deadly July compared to previous heatwaves, 2023 is already recording the highest summer mortality rate since the devastating heatwave of 2003. These figures do not yet include data from August, suggesting the final toll could be significantly higher. The current data indicates a continuing, serious public health crisis linked to extreme temperatures. Authorities are monitoring the situation closely as the summer progresses. The increasing frequency and intensity of heatwaves are raising concerns about long-term impacts on public health and mortality rates. This year’s data underscores the vulnerability of the population to extreme heat events.
